What is time? In this Cosmic Query, astrophysicist Neil deGrasse Tyson answers a fan who wonders whether time is more like Ray Bradbury’s linear depiction of time in “A Sound of Thunder,” the branching timestream depicted in 2009’s “Star Trek” or the way Doctor Who describes it in the classic episode “Blink”: “a big ball of wibbly, wobbly, timey-wimey…stuff.” Enjoy this “Behind the Scenes” video with comic co-host Colin Jost.

"...or the way Doctor Who describes it in the classic episode 'Blink': 'a big ball of wibbly, wobbly, timey-wimey…stuff.' ”

Didn't watch the clip, because I can't grasp physics; however one might postulate time doesn't exist, that time is only hominid measurement of motion; which brings in attempting to prove a negative or somesuch. No peer-reviewed material, as far as is known, written on the non-existence of time.
